Other mods in directories stored on that site are also affected.
That said, I think maybe did archive the mods after all though and I'm just lucky, but yes, it seems the mod is still downloadable, but the file directory on Simbology is broken at the moment. I decided then to just copy the link of the download to the url bar, then removed all the crap to directly link back to the Simbology site itself. I wonder if it's actually downloading from Simbology itself, as Wayback Machine will sometimes fallback to the original page, I think. I made an account here to say that I tried that and it works! But that's so very unusual for the Wayback Machine, as usually they don't archive anything more than webpages themselves.
